lIMPROVEMENT IN MACHINES FOR ROLLING PUDDLERS BALLS.

Specification forming part of Letters Patent No. 149,066, dated March31, 1874; application filed February 14, 1873.

To all whom it may concern:

Be it known that I, JAMES ROBERTSON, of Glasgow, in theveounty ofLanark, Scotland, have invented a certain new and useful Improvement inMachine for Blooming and partially forming Muck-Bar in the Manufactureof Iron; and I do hereby declare that the fol- -lowing is a full, clear,and exact description thereof, reference being had to the'accompanyingdra-win gs and to the letters Of reference marked thereon.

My invention relates to an improvement in a machine for blooming andpartially forming muck-bar in the process of manufacturing iron, thesaid machine consisting Of a carry in g-roll and two coniform rolls, aportion of the periphery of the latter being furnished with corrugationsof variable depth, which run longitudinally with the plane of theirsurface, and the other portion of their surface being smooth, and theiraxes arranged on planes at an acute angle to each other.

TO enable others skilled in the art to make and use my invention, I willproceed to'describe its construction and operation.

In the accompanying drawings, which form part of my specification,Figure l is a top view Or plan of my improvement in machine for bloomingand partially forming muck bar. Fig. 2 is an end elevation of the same.Fig. 3 represents the relative position of the two coniform rolls toeach other. Fig. 4 is a top View Of one of the coniform rolls, theperiphery of which is furnished with pyramidal projections andcorrugations.

A represents the base of the machine. B represents the housing orsupport for the bearings of the axes of the rolls. O C represent the twoconiform blooming and forming rolls, a portion of the periphery of whichis furnished with corrugations of variable depth, 'as indicated at e andf, the greatest depth being at e. D represents the carrying-roll, whichis arranged between the rolls C O', as indicated in Figs. l and 2. Theaxes of the rolls C C are arranged on different planes, and at an acuteangle to each other, as shown in Fig. 3.

By this arrangement of the rolls O O with relation to each other, thepuddled ball will be carried along on the roll D toward the smallerdiameter Of the rolls C C gradually forming the ball g into a bloom,which, at the plain part h of the rolls G C', is formed into a round barof partiallyformed muck-bar, as indicated at vl in Fig. l, all Of whichresult is accomplished by a single pass and heat.

The periphery of the roll's O O' may be provided with pyramidalprojections, as indicated at lo, and corrugations as at l, in Fig. 4,and the same results be obtained.

The drivin g-power may be applied to either of the axes m or u of therolls@ or O.

Having thus described my improvement, what I claim as of my invention isThe rolls O and O', having their peripheries provided with corrugationsof variable depth, and their axes arranged on different planes and at anacute angle to each other, in combination with the carryingroll D,substantially as herein described, and for the purpose set forth.

vIn testimony whereof I have hereunto set my hand the twenty-eighth dayof December, in the year of our Lord one thousand eight hundred andseventy-two. l

JAMES ROBERTSON.
